Hi. Last day I noticed that we could add some rules to the contest, there are a content http://en.wikipedia.org/wiki/Wikipedia:Image_use_policy#Contentrules to apply to images on wikis that we can add to our rules. That rules say that free images should not be watermarkedhttp://en.wikipedia.org/wiki/Digital_watermarking, distorted or have any credits in the image itself. We could add to this rules that the images should not have a frame, all this will make that uploaded images could be used directly in wiki articles and make them more "standarized".
What do you say?.
